What's Blooming? Companions

"Structure is the most important component in a successful planting," wrote Piet Oudolf in his book, Designing With Plants. Indeed, Oudolf believes that by concentrating on the structure of each plant, one can create a garden that is interesting to look at through several seasons, not just during bloom time. This was one of the principles employed when he designed the plantings of the Lurie Garden - selecting plants for their shape and structure to make interesting combinations.

One such combination can be found in the Dark Plate where he used plumes and spires at the south stairs. In the foreground, is a stand of an ornamental grass, Calamagrostis 'Karl Foerster' (Feather Reed Grass) in bloom this month with pinkish bronze inflorescences. It will grow to six feet, creating a screen to highlight the spires of Digitalis ferruginea (Rusty Foxglove) blooming in front. This Digitalis has smaller blooms, doesn't require staking, and makes a nice companion to the reed grass screen. Above and behind these plants, creamy white plumes of Persicaria polymorpha (White Dragon Knotweed) add another dramatic screen, calling attention to the tips of the Feather Reed Grass.

In the fall, the Digitalis will turn a sienna brown; the Calamagrostis inflorescences will blow out to buff-colored plumes; and the plumes of the Persicaria will become a lighter version of the Digitalis.

Tours begin at 10 am today. Look for signs pointing out Liatris spicata 'Alba,' Monarda didyma 'Scorpian,' and Agastache 'Blue Fortune.'

Finding Blooms on the Garden Tours

Today as you stroll through the garden, look for a vibrant medley of blue and violet perennials located in the Transition Area of the Dark Plate, overlooking the Seam. Here is a good example of the way in which Piet Oudolf used plant shapes to add interest to the garden.

Three kinds of globe-shaped flowers are interplanted for a natural look : bright blue Echinops bannaticus 'Blue Glow' (Globe Thistle); red violet Monarda didyma 'Scorpian, (Bee Balm); and the smaller, burgandy-clored Knautia macedonica (Knautia). In contrast, vertical spires of flower clusters define the space and draw the eye upward: lavender Veronica longifolia 'Evelyne' (Speedwell) at under 2 feet and the taller Veronicastrum virginiatum 'Temptation' (Culver's Root) that can grow to nearly five feet.

In bloom at the corner of the path, just south of this spot, is Astilbe chinensis 'Maggie Daley' (Astilbe), named for the first lady of Chicago. This violet lavender Astilbe is more compact than other varieties in the garden, standing about two feet tall with spires of branched pannicles that are densely covered with flowers. Its foliage is a deep green that is tinged with bronze. Maggie Daley will bloom late into summer, contrasting with the lavender spires of the Giant Hyssop across the path. This planting was an experiment last year - the garden staff tried to find another plant that could tolerate this sunny location.

Down the path and to the east of Maggie Daley is a 7-foot tall plant with huge, lettuce-green leaves - Inula magnifica 'Sonnenstrahl' (Fleabane). This perennial is magnificent if only for its foliage. Atop its sturdy stems are bright yellow daisy-like flowers with drooping petals, giving the appearance that each is wearing a grass skirt. Look beyond this planting to see similar yellow flowers of Silphium laciniatum (Compass Plant).

Garden Tours are from 10 am to 1:30 pm and last about 20 minutes. In addition to the plants mentioned above, look for Allium 'Summer Beauty,' Echinacea 'Orange Madowbrite,' and Stachys officinalis 'Hummelo.'

What's Blooming? Color!

While the violet-blues of the Salvia River continue to dominate, other plants are bringing more colors from the spectrum as the garden eases into its summer cloak. Reds, oranges and yellows can be found, making an effective contrast to the blues and purples of the meadow sage.

In the Light Plate, Echinacea 'Orange Meadowbrite' (Coneflower) can be found between the Salvia River and the Seam, growing through the delicate blades of an ornamental grass, Molinia caerulea 'Dauerstrahl' (Moor Grass). Look for Monarch butterflies lighting on the dark cones as they continue their migration through Illinois.

Above the Seam in the transition area of the Dark Plate, Knautia macedonica (Knautia) is opening before its companion plant, a daylily, Hemerocallis 'Gentle Shepherd' that will follow next month. If you are familiar with the lavender perennial pincushion flower (Scabiosa), you will see some similarities as they are both from the same family, Dipsacaceae. However, the flower of the knautia is claret red and only an inch across. As you traverse the stairs, notice that the red of the knautia echoes the color of the burnette on the opposite side.

The tallest plant in the Meadow is in bloom with bright yellow daisy-like flowers. Silphium laciniatum is commonly called Compass Plant because it can align its leaves north and south to reduce exposure to the hot sun and conserve moisture. This North American native can grow to 10 feet, towering above the Rattlesnake Masters and Green Edge Coneflowers that are interplanted throughout the Meadow. Beginning in late summer, the seeds of its cones will feed birds through the fall and into winter. Look for goldfinches perched along its stem, looking for food.

What's Blooming? Narcissus

Of the 120,000 bulbs that are planted in the Lurie Garden, tulips in colors of pink and violet are the showiest. But if you take a closer look you will find that the Narcissus play an equal part in the spring garden, bringing a contrast in shape and color. White and pale yellow narcissus act as a foil to the tulips, creating a light background that emphasizes the deep colors of the tulips.

Narcissus 'Lemon Drops' (Daffodil) were the first daffodils to be planted in the garden the the fall of 2006. Lemon Drops is a fragrant, tiandrus daffodil, having multiple flowers from one bulb. It has pale yellow petals with yellow, fluted cups and adds a natural look. In the Meadow, it mixes well with rosy Prairie Smoke, fuscia Shooting Stars and blue-violet Quamash.


N. 'Jenny' is similar to Lemon Drops and can be mistaken for it. When Jenny first opens, it has milky white petals and a sulphurous yellow cup. However, as the flower matures, the cup turns creamy white. Another distinction from Lemon Drops is that Jenny's petals are more pointed and arch away from the cup. One area to find Jenny is in a corner of the Dark Plate next to the Cloud Plaza.


N. Thalia is also a tiandrus daffodil with two to three fragrant, snow-white flowers to a bulb. It is distinguished from its cousins because of its pure white color and its long, open cup. A good viewing spot to see this beauty is at the top of the south stairs in the Dark Plate, under the blooming, pink Cercis canadensis.


N. Actaea is very different from the other daffodils. This fragrant daffodil has rounded white petals and a short yellow cup that is edged in dark red. Actaea is a member of group of narcissus known as Poet's Narcissus or Narcissus poeticus. It is considered an heirloom species, cultivated in 1919, and looks more like a wildflower growing in open land.

Lurie Garden Guided Walks

Guided Walks in the Lurie Garden begin Sunday. Docents, most of whom are University of Illinois Extension Master Gardeners, will be on hand to give free 20-minute tours of the garden.

While all sizes of tulips in shades of bright fuscia, lipstick red, golden yellow, white and dark blue-violet continue to dominate attention from visitors and photographers, take a closer look at some of the more subtle flowers that are opening.


Between the Cloud Plaza and the yew hedge, Fritillaria pallidiflora (Fritillary) is still blooming. This plant is a native to China and is used in the Lurie Garden for its hardiness and shape. It can withstand temperatures to -15F and its creamy yellow flowers mirror shape of tulip heads, gracefully nodding toward the ground. They brighten up and add texture to the Hosta 'Halcyon' whose leaves are at the height as the Fritillary.


Across the Plaza in the center of the Dark Plate, Epimedium x versicolor 'Sulphureum' (Bishop's Hat) forms a groundcover at the Plaza's edge. Its flowers are a sulphur yellow (hence the name) and are so small that they may be overlooked. What is eye-catching about this plant is its foliage. Heart-shaped green leaves, edged in reddish bronze, form soft mounds about a foot high. As they mature, the leaves continue to redden, outlining the veins that remain green.

Helleborus orientalis (Lenten Rose) opened in late April and will continue to flower through the month. The colors of this species vary from pale pink to deep violet. It is used in the garden for its early bloom time and because its foliage continues to look good throughout the year. In winter when patches of snow dot the garden, the leaves of the Lenten rose may be the only green in the garden.

Look for tour guides at the south end of the Seam, under the white awning.
